This inventionrelates to an improved apparatus .for manufacturingroller. and semiroller chains and the object ofthe invention is toprovide means for collating the different parts and for quicklyassembling the same with accurate adjustment.

The apparatus consists of two devices for collating the parts and adevice for assembling the parts made of cast metal with the bedsrecessed to receive the parts, and pro-, 'vided with movable members forholding the parts together and locking levers therefor, said beds beingformed integral with base plates which latter are adapted to be fastenedto a bench.

To fully describe the invention reference is now made to theaccompanying drawings in which Fig. 1, is a plan of the primarycollating device shown closed.

Fig. 2, is a plan of the secondary collating device shown open with theside cheek of a link in position.

Fig. 3, is a perspective view of the secondary collating device openshowing the side cheek and the distance bushes of a link.

Fig. 9, is a perspective view of a link complete. 7 V v Fig. 10, is aplan of one cheek and elevation of a distance bush.

Fig. 11, is a plan view showing two hushed links, and one incompleterivet link, before assembling.

Fig. '12. is a plan view showing two hushed links and one rivet linkassembled.

In Figs. 1, 2, and 3, 1 is the base plate having slots l at the end forbolting down on to a bench.

2 is the bed of the device which as shown in Figs. 2 and 3 is recessedto receive the side checks of the link while the bed in Fig. 1 is plain.I

The bed is formed integrally with a superimposed solid side member 3; inFigs. 2 and 3 they are rabbeted on the underside to accommodate thecheeks of the links; on to the top of the side member is fitted plate 4for holding'the cheeksera. links-inns curateposition and the solid sidemember 3 in Fig. 3 is vertically grooved whichito gether with verticalgrooves 5 in'the'hirrged jig 5, Fig.""3, hol'dthe rivets 8 in accurateposition. bin-Figs.

In Figs. 4 and 5 which illustrate the assembling device 1 is the baseplate, 2 the bed, 3 the superimposed solid side member fitted with plate4 for holding the checks of the links inaccurate position. 9 representsa groove in the bed to accommodate the end of the rivets. f V

The bed is slotted on one side asindicated at 2 in which is fitted aspiral spring'IO; a slide block 11' formed integral with a lug 11 fitsinto the slot 2 said slide block locked hy the eccentric lever 6. 12 isa stop to arrest the movement of the slide block 11. The solid member 3is rabbeted on its underside to accommodate thecheeks of the links. V r

In using the invention two shouldered distance bushes are put in theprimary collating device which is then closed by the eccentric lever 6,a cheek is then placed on the shouldered distance bushes and pressed hyaplunger to fix the same together, the combination is then removed,reversed and placed in the secondary collating device which isthenclosed and locked by the eccentric lever and a cheek placed on to theshouldered distance bushes and pressed by a plunger which completes onehushed link.

To make a rivet link, rivets are placed in I a similar collating deviceas used for the hushed links with the exception thatthe holes in samefor holding the rivets are smaller, a cheek placed on top and pressed by2; plunger, when one half of a rivet link is mac e.

To assemble the hushed and rivet links to form a chain a hushed linkisplaced on each rivet of the rivet link, then placed in an assemblingdevice illustrated by Figs. 4 and 5 and a cheek placed on top of therivets and Dressed by av plunger which completes a length of chainconsisting of arivet link and two hushed links, the operation isrepeatedto make a continuity of the chain, the hushed] the" internallinksuaildtherivet theIexternal'li'nks, j r'f b c v ,gya forwardeccenltr mov ment-clam s? thej chai'n in imsi ivb egil ,i iwma h F "1eeem e by: Letters; Patent is 1 Appa'rat 's for rmenuf actu r mgi reliefand interalYtherewith, a sidemember'inteipm tibne of the link,ta movablymounted 6n the'ilpper s'ilrfacep Aftlfthdfl chain isf fisseiphlfedj thelinksiere' eemrmHer-I Ch'aiii's'f including a base plate, a
